Here's how to restore the View Image entry in Firefox right click menu for images.
In Firefox 88, Mozilla has silently removed a number of context menu entries. Speaking of the View Image option, it has been replaced with an "open image in a new tab" entry. The team behind the browser assumes that most users will be happy with the new item that opens the image you right-click on in a new tab. However, some users prefer the old behavior of the browser with the ability to open images in the current tab.
